Car Heater Hoses

Whatever the season is, you wouldn't want either of your car's climate control systems to fail. And it's not just because AC or heater failure means you would have to repair or replace something in them. A more important reason is that a failure in any of these two systems could lead to other more serious problems in your ride. Take, for example, the consequences if a heater hose in your ride gets damaged.

By the component's name itself, you would know that it belongs to the heating system of your car. Still, many confuse it with a radiator hose; they think the two hoses are the same-after all, the coolant that passes through the heater hoses also passes through the radiator hoses, right? Well, that's true. In fact, they're not only the same in terms of the liquid they handle. More or less, the two hoses are also made of the same stuff, which is basically high-temperature-resistant rubber with a reinforcement of woven synthetic threads. But then, these hoses are just too simple to be called different names. To distinguish them, simply take their names as a clue: the one connects to the heater core and the other connects to the radiator.

Now, there are at least two car heater hose units in your ride. Both are connected to the heater core, but one serves as the inlet pipe, while the other as the coolant's outlet. When you turn on your car's heating system, the heater valve opens and lets part of the coolant from the engine to be diverted into the heater core via the inlet hose. The heater core, being a mini radiator with its tiny tubes and fins, give off the coolant's heat into the cabin with the help of the blower fan. After releasing heat, the coolant then leaves the heater core via the outlet hose to go back to the engine to absorb heat again.

With a heater hose's functions, you'd definitely be in trouble if one of them gets broken or clogged. Leaks will not only keep your heater from warming up your cabin; they will also drain your cooling system of the precious coolant that keeps the engine from overheating. So, inspect them from time to time. Check each heater hose for visible signs of leak and damage. If there are none, try squeezing them gently. If they crack under the pressure you exerted, or if they already feel brittle or softer than when they were new, then you'd have to replace them soon as possible.
